CAMBRIDGE -- Katie Newton works for Lanni Orchards in Lunenberg. Twice a week in the harvest season, the family farm sends freshly picked fruits and vegetables to Kendall Square, where Newton moves it from the truck to a tent. Jerry Lanni, one of the owners of the farm, says the produce is picked either that morning of the afternoon before. The rise of interest in the buying locally-grown crops has given area farmers like Lanni an eager group of customers. "The world spends too much energy shipping food around the world," says shopper Gordon Beadle of East Cambridge. "Most people don't think about how much energy it takes to get it here. So I'd rather support some local economics."
